That's the part that interests me.
You still want carbs, they are a player in the same fatigue process. BCAAs may mitigate a lack of carbs but carb + BCAA might be additive.

RESULTS: About 106 micromol (22 mg) of tryptophan was taken up by the brain during exercise in the placebo [water] trial, whereas no significant uptake was observed in the carbohydrate trial. ...CONCLUSION: The present data show that both tryptophan and BCAA are taken up by the brain during prolonged exercise, and we suggest that the cerebral uptake of tryptophan may relate to increased synthesis of serotonin (5-HT) in the brain.
